Quick Detail

Description

The 330105-02-12-05-02-CN 3300 XL 8 mm Reverse Mount Probe is a high-precision eddy current proximity transducer component engineered by Bently Nevada, designed to deliver unparalleled accuracy and reliability for industrial machinery condition monitoring. As a core part of the 3300 XL transducer system, this reverse mount probe features a compact structural design with an overall case length of 60 mm (2.4 inches), 0 mm minimum unthreaded length, and ultra-lightweight of 0.03 kg, making it the optimal solution for space-constrained installation scenarios where traditional probes fail to fit. Equipped with a Miniature ClickLoc coaxial connector and 0.5-meter (1.6-foot) cable, the 330105-02-12-05-02-CN probe ensures secure, quick-connect installation while maintaining high-fidelity signal transmission for both static position and dynamic vibration measurements.

What sets the 330105-02-12-05-02-CN 3300 XL 8 mm Reverse Mount Probe apart is its industry-leading compliance with the American Petroleum Institute (API) 670 standard, a benchmark for reliability in critical turbomachinery monitoring applications. This compliance guarantees exceptional linear measurement range (2 mm / 80 mils), temperature stability, and data accuracy, even in extreme operating conditions ranging from -52°C to +177°C (-62°F to +341°F). Constructed with AISI 303/304 stainless steel case and polyphenylene sulfide (PPS) probe tip, the probe exhibits superior resistance to corrosion, mechanical wear, and chemical erosion, ensuring long-term durability in harsh industrial environments such as petrochemical refineries, power generation plants, and offshore drilling platforms.

Applications

The 330105-02-12-05-02-CN 3300 XL 8 mm Reverse Mount Probe is ideally suited for space-constrained machinery monitoring scenarios where traditional probes cannot be installed. Its compact dimensions (1.1x1.1x60 cm), 0 mm minimum unthreaded length, and 60 mm overall case length enable seamless integration into narrow cavities of rotating equipment, tight fluid-film bearing assemblies, and compact precision instruments. In these applications, the probe accurately captures static position data such as rotor axial displacement and dynamic vibration signals, helping maintenance teams detect potential faults like shaft misalignment, bearing wear, and rotor imbalance at an early stage, thus preventing costly equipment downtime.

This reverse mount probe excels in extreme and hazardous industrial environments, thanks to its CSA, ATEX, and IECEx certifications and wide operating temperature range of -52°C to +177°C. It is widely deployed in petrochemical refineries, offshore drilling platforms, and coal-fired power plants to monitor critical machinery including centrifugal compressors, gas turbines, and reciprocating engines. In these high-risk settings, the probe’s corrosion-resistant AISI 303/304 stainless steel case and PPS probe tip ensure reliable performance even in the presence of corrosive chemicals, high humidity, and intense mechanical vibration, while its explosion-proof design eliminates ignition risks in flammable atmospheres.

As a key component of predictive maintenance systems, the 330105-02-12-05-02-CN 3300 XL 8 mm Reverse Mount Probe supports Keyphasor reference signal collection and rotational speed measurement, enabling comprehensive condition monitoring of rotating machinery. Its backward compatibility with non-XL 3300 series components makes it a cost-effective upgrade solution for legacy monitoring systems in steel mills, automotive manufacturing plants, and aerospace ground support facilities. By integrating this probe into existing setups, users can enhance measurement accuracy, extend equipment service life, and optimize maintenance schedules, ultimately improving overall operational efficiency and reducing long-term maintenance costs.

Specifications

Competitive Advantage

1.Ultra-Compact Reverse Mount Design for Space-Limited Installations

Unlike conventional proximity probes that require ample installation clearance, the 330105-02-12-05-02-CN 3300 XL 8 mm Reverse Mount Probe features a specialized reverse mount structure with 0 mm minimum unthreaded length and 60 mm compact case length. This design allows it to fit into narrow cavities, tight bearing assemblies, and compact precision instruments where standard probes cannot be deployed, eliminating the need for costly equipment modifications or custom part fabrication. Its lightweight (0.03 kg) and small footprint (1.1x1.1x60 cm) further simplify handling and installation, making it the top choice for space-constrained industrial applications.

2.API 670 Compliance & Extreme Environmental Resilience

The probe meets the stringent requirements of API 670, the global standard for turbomachinery protection systems, ensuring superior linear measurement range (2 mm / 80 mils), data accuracy, and temperature stability. With an operating temperature range of -52°C to +177°C, it performs reliably in both freezing cold and high-heat industrial environments, outperforming competing probes with narrower temperature tolerances. Constructed with AISI 303/304 stainless steel case and PPS probe tip, it offers exceptional resistance to corrosion, abrasion, and chemical erosion, extending service life by 40%–60% compared to ordinary probes in harsh settings like offshore drilling and petrochemical processing.

3.Full Interchangeability & Cost-Effective Legacy System Compatibility

A core competitive edge of the 330105-02-12-05-02-CN probe is its seamless interchangeability with all 3300 XL series extension cables and Proximitor sensors, eliminating the need for calibration or component matching during replacement. This plug-and-play functionality reduces maintenance downtime by up to 70% compared to non-interchangeable alternatives. Additionally, its backward compatibility with non-XL 3300 series 5 mm and 8 mm transducer components allows users to upgrade legacy monitoring systems without replacing the entire setup, significantly lowering upgrade costs and protecting initial capital investments—an advantage that competing probes with limited compatibility cannot match.

4. Multi-Certified Safety for Hazardous Area Deployment

Equipped with CSA, ATEX, and IECEx certifications, the probe is fully compliant with international explosion-proof standards, enabling safe deployment in flammable gas, vapor, and dust-rich hazardous areas. Unlike generic probes that require additional protective enclosures for hazardous environment use, this product eliminates compliance risks and extra costs associated with secondary safety modifications. Its certified design ensures that it does not ignite explosive substances during operation, making it a trusted choice for critical applications in oil refineries, chemical plants, and mining operations.
